Water-proof package carton board

Abstract

The invention discloses a water-proof package carton board which comprises surface paper, core paper and inner paper, wherein the core paper is arranged between the surface paper and the inner paper;the package carton board further comprises water-proof layers; the external surfaces of the surface paper and the inner paper are coated with the water-proof layers; the water-proof layers adopt water-proof paint; and the water-proof paint is prepared from the following raw materials in parts by weight: 50-80 parts of polyacrylic resin, 10-20 parts of rosin, 10-20 parts of an asbestos powder, 5-8parts of a defoaming agent, 6-12 parts of a film formation assistant, 8-18 parts of an antioxidant and 20-30 parts of deionized water. With the adoption of the mode, the water-proof package carton board is mainly used for a package carton, is high in structural strength, has a good water-proof effect and a better heat insulation effect and facilitates transportation; a material can be recycled; the package carton board is environment-friendly; and the production cost is lowered.

Description

technical field [0001] The invention relates to the field of packaging, in particular to a waterproof packaging carton board. Background technique [0002] Because the cost of paper packaging materials is low and can be recycled and recycled, most of the existing packaging materials are made of cardboard, but the packaging cardboard is not waterproof, and it is easy to deform after being damp, which affects the quality of the items in the package. At the same time, The packaging cardboard itself is weak in strength, and it is often squeezed and deformed during transportation, which also affects the quality of the items in the package. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a waterproof packaging carton board, which is mainly used for packaging cartons, has high structural strength, good waterproof effect, and good heat insulation effect, which is convenient for transportation and use. It can be recycle...
